Do catalyst allow chemical reaction to take place at zero degree celsius?
Some catalysts can increase the rate of a chemical reaction at zero degrees Celsius, but not all catalysts are effective at such low temperatures. The effectiveness of a catalyst at low temperatures depends on the specific reaction and the nature of the catalyst.
What ways can a catalyst affect a chemical reation?
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
How a catalyst effects chemical reaction?
Catalysts allow chemical changes to occur much more rapidly. Reactions that usually take years can happen before your eyes in seconds. From my understanding there is no 100% agreed upon reason for how they do this. There are a number of widely regarded theories though.
How does a catalyst work?
A catalyst actually decreases the activation energy of a reaction in 2 ways: 1) By a process called adsorption, it attracts the molecules of the reactants to its surface so that they are closer together and can react more easily by colliding more successfully. 2) It creates a transition state, which is an inter mediate state before the final reaction occurs, which creates an intermediate, unstable compound using the catalyst itself. By the time the final product is formed, a new product as well as the original catalysy are remaining and the activation energy is considerably reduced.

Are substrate and catalyse the same thing?
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
How is a catalyst different from the reactants and products of a chemical reaction?
A catalyst is not consumed in a chemical reaction, unlike reactants that are consumed to form products. Catalysts lower the activation energy required for a reaction to occur, increasing the reaction rate without being permanently changed or used up in the process. Reactants are the starting materials that undergo a chemical reaction to form products, which are the final substances produced at the end of the reaction.

What is molecules which serve as chemical to make reactions work?
Molecules or compounds that function to allow a reaction to take place but do NOT take place in the reaction itself are called catalysts. Biological catalysts made of proteins are called enzymes.

What effect would a catalyst have on the reaction A2 plus 2B ---- 2AB?
A catalyst would increase the rate of the reaction by providing an alternative pathway with lower activation energy. This would allow the reaction to occur more quickly without being consumed in the process. The equilibrium concentrations of the reactants and products would remain the same.
How do enzymes control the rate of reaction?
Not exactly. An enzyme is a form of catalyst. Organic in nature, they can be astonishingly powerful compared to the inorganic catalysts such as platinum, nickel or water. A catalyst generally speeds up a reaction. The control of reaction speeds in the body usually involves two enzymes, one a catalyst and the other an antagonist which interferes with the function of the first one. Some form of feedback loop finely adjusts the amounts of each of these, and the balance controls the speed of the reaction.
Why v2o5 act as a catalyst?
V2O5 acts as a catalyst because it can provide an active surface for the reaction to occur by adsorbing reactant molecules and providing a pathway for the reaction to proceed. Additionally, the variable oxidation states of vanadium in V2O5 allow it to easily switch between different oxidation states during the catalytic reaction, making it an effective catalyst.
Is mixing chemicals a chemical reaction?
The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
